Wait wait wait wait wait. So you're saying that a configure script that compiles a 5-line test program (and does this 50 times) to check if a feature is present or a compiler flag works... will have to call out to Apple for permission to do so??

Ugh. Disgusting. So glad I stopped using macOS years ago. (Even if this isn't actually true... still glad I stopped using Apple's we-know-better-than-you OS years ago.)

It is amazing to me that people put up with this garbage and don't use an OS that respects them more.
